From 56d26ade97135614ccc60cb215d6c9cb22babfb1 Mon Sep 17 00:00:00 2001 From: Victoria Dye Date: Tue, 14 Nov 2023 19:53:49 +0000 Subject: ref-filter.c: really don't sort when using --no-sort When '--no-sort' is passed to 'for-each-ref', 'tag', and 'branch', the printed refs are still sorted by ascending refname. Change the handling of sort options in these commands so that '--no-sort' to truly disables sorting. '--no-sort' does not disable sorting in these commands is because their option parsing does not distinguish between "the absence of '--sort'" (and/or values for tag.sort & branch.sort) and '--no-sort'. Both result in an empty 'sorting_options' string list, which is parsed by 'ref_sorting_options()' to create the 'struct ref_sorting *' for the command. If the string list is empty, 'ref_sorting_options()' interprets that as "the absence of '--sort'" and returns the default ref sorting structure (equivalent to "refname" sort). To handle '--no-sort' properly while preserving the "refname" sort in the "absence of --sort'" case, first explicitly add "refname" to the string list *before* parsing options. This alone doesn't actually change any behavior, since 'compare_refs()' already falls back on comparing refnames if two refs are equal w.r.t all other sort keys. Now that the string list is populated by default, '--no-sort' is the only way to empty the 'sorting_options' string list. Update 'ref_sorting_options()' to return a NULL 'struct ref_sorting *' if the string list is empty, and add a condition to 'ref_array_sort()' to skip the sort altogether if the sort structure is NULL. Note that other functions using 'struct ref_sorting *' do not need any changes because they already ignore NULL values. Finally, remove the condition around sorting in 'ls-remote', since it's no longer necessary. Unlike 'for-each-ref' et. al., it does *not* do any sorting by default. This default is preserved by simply leaving its sort key string list empty before parsing options; if no additional sort keys are set, 'struct ref_sorting *' is NULL and sorting is skipped.
